In addition, it is preferable that each spout is extended in the axial direction (longitudinal direction) of the water sprinkling portion 6. By providing the spout in this way, the range of spouting water can be widened. Further, in the water sprinkling portion 6, water passages communicating with the respective water outlets are formed, respectively, and further, in the water sprinkling portion 6, a passage switching member 4 provided integrally with the joint 2 is rotatable in the circumferential direction.

It is configured to be in a state. In the following specific embodiments, two pulsating water outlets and a spray water outlet are arranged as water outlets, and a water passage hole B19 formed in the inner cylinder 6 and a spray inflow passage 21 are formed as water outlets. A case will be described. Then, this water passage hole B19 passes through the inner side of the inner cylinder 6, and the spray inflow passage 21
Allows the water to pass through the outside of the inner cylinder 6 to the water outlet communicating with them. The inner cylinder 6 has a substantially cylindrical outer shape. In addition, although the water passage of two paths was formed using the separate inner cylinder 6, this inner cylinder 6 may be integrally formed with the water sprinkling portion 6.

Further, pulsating water discharge can be performed as one of the water discharge forms of the water discharge device A.
That is, the draining member 16 is provided as a functional part to be housed in the inner cylinder 6.
And a pulsating water discharge function section mainly composed of the impeller 14. By storing this functional part in the inner cylinder 6, the hot and cold water discharged from the sprinkling part 6 can be intermittently discharged in a pulsating manner.

The term "pulsating water discharge" as used herein means a water discharge which is intermittent by continuously repeating water-stopping / water-jetting at the time of water discharge. What is spray spouting?
At the time of water discharge, it is not the intermittent water discharge like pulsating water discharge but the water discharge in which the water discharge state is always maintained.

As shown in FIGS. 1 and 2, the water discharger A
At the end of the water sprinkling portion 6, the flow path switching member 4 provided with the hot and cold water supply port 1 is provided. The side surface of the water sprinkling portion 6 of the water spouting device A is provided with a plurality of pulsating water spouts 7 for pulsating water spouting and a plurality of spray water spouting ports 8 for spray water spouting in the axial direction. FIG. 3 shows a cross-sectional view when the pulsating water discharge of FIG. 1 is performed. Flow path switching member 4 provided with hot and cold water supply port 1
Is provided with a joint 2, and the joint 2 is provided with a flow path switching member 4
Is fitted in a watertight state by packing 3,
Spring 5 constantly supplies hot water (inner cylinder 9 side)
Is urged by. The joint 2 of the flow path switching member 4 and the inside of the water sprinkling portion 6 are rotatably joined to each other. A recess is formed on the entire circumference of the side surface of the joint 2, which is the rotating portion, so that the packing 3 is embedded. ing. The packing 3 maintains watertightness and also serves as resistance when the water sprinkling portion 6 rotates.

An inner cylinder 9 is fitted in the water sprinkling portion 6, and an oscillating water discharge passage 11 and a spray water discharge passage 1 are provided by an O-ring 10.
2 and are watertight. Then, this pulsating water discharge channel 11
And the spray water discharge passage 12 are connected to the pulsating water discharge port 7 and the spray water discharge port 8, respectively.

Inside the inner cylinder 9, the shaft 13 has a draining member 16
Is fixed so as to be sandwiched between the impeller 14 and the fixing member 15. The draining member 16 and the impeller 14 are integrally formed, and are provided independently of the water sprinkling portion 6 and the inner cylinder 9, and are rotatably fitted between the inner cylinder 9 and the cover 17. ing. Further, the water sprinkling portion 6 itself is also screwed by the closing lid 17, and is rotatably attached to the joint 2 in conjunction with the inner cylinder 9. In addition, the cross-sectional portion surrounded by the one-dot chain line in the lower left of the figure shows the cross-sectional view of the portion rotated by 90 degrees from the other cross-sectional portions.

As shown in FIG. 3, when the hot water is supplied through the hot water supply port 1 of the joint 2 in the state where the water is switched to the pulsating water discharge side, the inside of the water flow hole A18 of the flow path switching member 4 is communicated. It is supplied through the impeller 14 through the water passage hole B19 of the cylinder 9 into the inner cylinder 9. At this time, the impeller 14 is rotated by the passage of hot water, and the draining member 16 interlocked with the impeller 14 is rotated. As shown, the impeller 14 is preferably formed at the upstream end of the draining member. As a result, the hot and cold water that passes through must pass through the impeller 14 and becomes the driving force for rotating the impeller 14.

The draining member 16 is provided with a water passage hole C20 so as to communicate with the pulsating water discharge passage 11 of the inner cylinder 9,
Hot water is discharged from the pulsating water discharge port 7 through the pulsating water discharge flow passage 11 from the inside of the inner cylinder 9 through the water passage hole C20. On this occasion,
Since the impeller 14 rotates, the draining member 1 that interlocks with the impeller 14 rotates.
6 also rotates, and at least any one of the pulsating water discharge passages 11 (pulsating water discharge ports 7) is changed to a water-flowing state, and another pulsating water discharge flow channel 11 (pulsating water discharge port 7) is formed with a water passage hole C20. By closing the draining member 16 in the non-exposed portion to bring it into a water-stopping state, the communication between the water passage hole C20 and the pulsating water discharge passage 11 (pulsating water discharge port 7) becomes intermittent, and hot water stops water flow / stop water. Pulsating water discharge can be obtained continuously and alternately.
As described above, by forming the water passage hole C20 on the side surface of the draining member 16, the water passage hole C20 can be formed regardless of the diameter of the impeller 14, so that the diameter of the impeller 14 can be increased, It is possible to provide an inexpensive and slim water discharger without using a plurality of impellers 14.

When the water sprinkling portion 6 is rotated in order to switch to the spray water discharge, the water passage hole B19 of the inner cylinder 9 which is interlocked with the water sprinkling portion 6 is also rotated and the water passage to the water passage hole A18 is cut off. Then, as shown in FIG. 4, the hot and cold water flows through the water passage hole A18.
Through the spray inflow passage 21 of the inner cylinder 9 into the spray water discharge passage 12 outside the inner cylinder 9 and discharged from the spray water discharge port 8.

Next, regarding each component, based on the drawings,
explain. As shown in FIGS. 5 and 6, the flow path switching member 4 has a substantially disc shape and is formed with two water passage holes A18 facing each other, and is rotated by 90 degrees with respect to the water passage holes A18. The protruding portion 4A is provided on the lower end side of this position. The protrusion 4A is fitted into the joint 2 as shown in FIGS. 3 and 4. Further, a packing accommodating portion 3A is formed on the side portion, and a concave portion 4B for accommodating the spring 5 for pressing the flow path switching 4 member in a watertight manner is provided on the inner cylinder 9 side.

As shown in FIG. 7, the bottom surface of the inner cylinder 9 is formed by offsetting the collar portion 19B and the spray inflow passage 21 by 90 degrees in the rotational direction. Then, two water passage holes B19 are provided in the collar portion 19B so as to face each other. Further, a packing housing portion 19A for housing packing is formed on the outer periphery of the water passage hole B19. Also, as shown in FIG.
A plurality of convex portions 11A are formed on the side surface of the inner cylinder 9 in the axial direction, and the pulsating water discharge flow passage 11 is formed in the convex portions 11A. The inner cylinder 9 is provided on the outer periphery of the pulsating water discharge flow passage 11.
An O-ring accommodating recess 11B for keeping watertight is formed. A similar convex portion 11C is also formed on the side surface opposite to the convex portion 11A. As shown in FIGS. 3 and 4, since the inner cylinder 9 is formed integrally with the water sprinkling portion 6, the inner cylinder 9 is also rotated by 90 degrees by rotating the water sprinkling portion 6 by 90 degrees.
The water is rotated by 0 degree and water is selected by selecting either the water passage hole B19 formed in the bottom surface of the inner cylinder 9 or the spray inflow passage 21. With this, as described above, pulsating water discharge and spray water discharge can be selected.

The water sprinkling portion 6 of the flow path switching member 4 is constructed so that the hot water supply port 1 and at least one of the water flow ports B19 always rotate while maintaining a water flow state. For example, as a preferable mode, the flow path switching member 4 is provided adjacent to the end of the water passage port A18 communicating with the hot water supply port 1. Further, among the water passage openings B19 provided in the water sprinkling portion 6, the distance between the water passage openings B19 adjacent to each other in the rotation direction of the water sprinkling portion 6 is the water passage opening A1.
Make it smaller than 8. Then, as shown in FIG. 14, the water passage port A18 is made to overlap both the water passage ports B19 adjacent to each other at the time of switching rotation.

Further, since the spouting portion 6 is formed with the spouting ports 7 and 8 of different spouting forms offset by a predetermined angle (90 degrees), it is recognized that the spouting form is switched by rotating the water spouting form by a predetermined angle. It is preferable to be able to do so. For example, as a preferable mode, as shown in FIG. 14, a stopper portion 35 that comes into contact with the water sprinkling portion 6 and the flow path switching member 4 at a predetermined angle (90 degrees) in the rotation direction of the water sprinkling portion 6 is provided. Is preferred.

FIG. 9 shows the draining member 16. It has a cylindrical shape so that it can be inserted into the inner cylinder 9 and rotated. Further, as shown in FIGS. 10 to 13, a water passage hole C2 is formed on the side portion.
Three are formed by shifting 0 by 60 degrees. The angle of each water passage hole C20 to be displaced in the rotational direction may be set according to the form of pulsating water discharge, and the number of water passage holes C20 may be set according to the number of pulsating water discharge ports 7. However, it is necessary to ensure that the end portions of the water passage holes C20 are facing each other without a gap in the rotation direction or overlap each other so that water is constantly discharged from the pulsating water discharge port 7 somewhere. That is, the impeller 14 is rotated by the water flow to perform pulsating water discharge, and the impeller 14 must always be rotated. Alternatively, in order to constantly rotate the impeller 14, a continuous spout (not shown) that constantly spouts water may be provided downstream of the impeller 14 in addition to the pulsating spout 7. In this case, the draining member 16 (pulsating water discharge port 7) can be formed on the upstream side of the impeller 14.
Further, in the figure, the water passage holes C20 are provided on the side surface of the draining member 16 by the number corresponding to each pulsating water discharge port 7, but the water passage holes C20 are provided.
One may be formed in a spiral shape on the side surface of the draining member 16 so as to block the alternately pulsating water discharge port 7.

The draining member 16 may be movable in association with the rotation of the impeller 14. Therefore, the draining member 16
May be integrally formed with the impeller 14 or may be formed separately. However, in consideration of the assemblability to the water sprinkling portion 6, it is preferable that the draining member 16 is formed integrally (including the integral) with the impeller 14.

FIG. 14 shows the water passage A at the time of switching the flow path.
18 shows the water flow relationship between the water flow port B19 or the spray inflow path 21, and the positional relationship of the stopper portion 35. FIG. 14 (A) shows a case where water is passed through the inner cylinder 9 to perform pulsating water discharge. In this state, the water passage A18 and the water passage B19 overlap each other. At this time, the stopper portion 35 is also in contact with one side surface of the collar portion 19B formed on the inner cylinder 9. FIG. 14B shows a state in the middle of switching the water discharge form. At this time, the water passage A18 is in a state of overlapping both the water passage B19 and the spray inflow passage 21. FIG. 14 (C) shows a state in which water is passed to the outside of the inner cylinder 9 to perform spray water discharge. In this state, the water passage A18 and the spray inflow passage 21 overlap each other. At this time, the stopper portion 35 is also in contact with the other side surface of the collar portion 19B formed on the inner cylinder 9.

In the embodiment described above, FIG.
As shown in FIG. 15, the hot and cold water supply port 1 is provided in the axial direction of the impeller 14, but as shown in FIG.
May be provided in a direction perpendicular to the axial direction of the impeller 14. FIG. 15B is suitable for a shower bar 33 type described later.

Next, another embodiment will be described with reference to FIG. The same parts as those in the first embodiment shown in FIGS. 3 and 4 are omitted, and other embodiments relating to pulsating water discharge are shown. As shown in FIG. 16, a hot and cold water supply port 1 is formed at the lower end of the water sprinkling portion 6. The hot and cold water is supplied from the hot and cold water supply port 1 via the impeller 14 to the sprinkler section 6.
Flows in. The impeller 14 is adapted to rotate as hot water passes. Further, on the outer circumference of the impeller 14, a cam 14A is formed in which a portion that comes into contact with the draining member 16 moves up and down as the impeller 14 rotates. Further, a biasing means 36 such as a spring is provided on the opposite side of the draining member 16 and biases the draining member 16 so as to push it toward the impeller 14. FIG. 16A shows a case where the contact portion of the cam 14A is located at the lower end and is biased by the biasing means 36 so that the draining member 16 is positioned at the lowermost end. FIG. 16B shows a case where the contact portion of the cam 14A is located at the upper end and the draining member 16 is located at the uppermost end. In this embodiment, the rotational movement of the impeller 14 is converted into vertical movement and transmitted to the draining member 16. Then, as the draining member 16 moves up and down, the pulsating water discharge passage 11 provided in the water draining member 16 overlaps or deviates from the pulsating water discharge port 7 provided in the water sprinkling portion. As a result, pulsating water discharge can be obtained by alternately repeating the water flow state and the water stop state.

Next, an application example of the water discharger A will be described with reference to the drawings. FIG. 17 shows a case where the water discharger A is applied to the shower nozzle 30. The shower hose 32 is connected to one end of the handshake 30A, and the joint 2 of the water discharger A is connected to the other end. The handshake 30A is provided with a water passage operation section 31 for switching between water passage and water stoppage to the water discharger A. By pushing the water passage operation section 31, water passage and water stoppage are performed. Water is discharged from the water sprinkling unit 6 toward the front where the water passage operating unit 31 is arranged. The figure shows a state in which the pulsating water discharge port 7 is arranged coaxially with the water flow operation unit 31, and when the water flow operation unit 31 is pushed to bring it into the water flow state, the pulsating water discharge port 7 is shown.
Pulsating water discharge is obtained from. Further, when it is desired to switch to spray water discharge, the water sprinkling portion 6 is rotated by 90 degrees so that the spray water discharge port 8 is arranged coaxially with the water flow operation portion 31. Since the water discharger A can be formed in a cylindrical shape, the handshake 30A can also be formed in the same cylindrical shape to form the slim shower nozzle 30.

Next, FIG. 18 shows a case where the water discharger A is applied to a shower bar (including a handrail) 33 formed of a pipe material or the like. The shower bar 33 is attached to a wall of a bathroom, a shower room or the like by an attachment portion 34.
The water discharger A described above is incorporated in the shower bar 33, and the water discharge state can be secured by disposing the water discharge port in the front. When it is desired to switch the water discharge form, it can be performed by rotating the water sprinkling unit 6 by 90 degrees as described above. As shown, this water discharger A
Since it can be formed into a cylindrical shape, it has the same diameter as the shower bar 33 and can be incorporated without bulging from the shower bar 33. Although not shown, the shower bar 33 itself may be used as a pipe for supplying hot water to the water discharge device A, or a pipe for supplying hot water to the water discharge device A may be inserted into the shower bar 33. .
